B) Iron is produced from its ore by the reactions:
2C(s)+O2(g) â 2CO(g)
Fe2O3(s)+3CO(g) â 2Fe(s) + 3co2(g)
How many moles of O2(g) are needed to produce 9.5 moles of Fe(s)?
C) Which of the following equations correctly describes the combustion of CH4and O2to produce water (H2O) and carbon dioxide (CO2)?
a) CH4 + O2 ï® CO2 + H2O
b) CH4 + O2 ï® CO2 + 2H2O
c) CH4 + 2O2 ï® CO2 + 2H2O
d) CH4 + 3O2 ï® 2CO2 + H2O
e) 2CH4 + 3O2 ï® 2CO2 + 2H2O
D) What is the coefficient for oxygen when the following equation is balanced?
NH3(g) + O2(g) â NO2(g) + H2O(g)
